Gas Discharge Tube Arresters (GDT)

SL1021A090RF is a type of gas discharge tube (GDT) arrester. It is typically used in high voltage network applications in order to provide protection against lightning surges, voltage transients, and other overvoltage transients. GDTs serve a vital role in the protection of electrical infrastructure, as these transient overvoltages can cause damage to sensitive equipment and even cause power outages.

SL1021A090RF GDTs are constructed of two electrodes; a main electrode and an internal electrode shielded in a gas-filled tube of porcelain or other ceramic material. The main electrode is commonly referred to as the “shield” and is connected to the equipment or circuit being protected. The internal electrode is connected to ground. When a voltage transient is applied to the GDT, an electric arc is created between the two electrodes. This ionization of gas in the tube greatly increases its electrical resistance and, consequently, attenuates the applied voltage.

SL1021A090RF GDTs can be used in a variety of applications. They are widely used in high-voltage power distribution applications, particularly those involving lightning protection. GDTs provide an effective solution for reducing the magnitude of surges in overhead distribution lines due to lightning and other sources of transient overvoltage. Additionally, they can be used in telecommunications networks, industrial control systems, automation systems, and other applications where large transient overvoltages may occur.

SL1021A090RF GDTs also have other benefits. They are relatively small and light, so they are easy to install in confined spaces. They are also durable and offer a long service life, making them a reliable, cost-effective protective device. Finally, GDTs are self-restoring and require no maintenance or servicing, saving time and money by eliminating the need to replace the protector after each event.

In conclusion, SL1021A090RF GDTs are a reliable, cost-effective solution for protecting against lightning surges, voltage transients, and other overvoltage transients. They are small and easy to install, durable, and require no maintenance or servicing. As such, they are a popular choice for many high-voltage power distribution and other applications.
